JEWELERS TOOL.

Specification of Letters Patent.

Patented Feb. 22, 1916-.

Application filed July 29, 1915. Serial No. 42,597.

To all whom it may concern.-

Be it known that I, ALFRED A. TURNAGE, a citizen of the United States,residing at the city of San Jose, in the county of Santa Clara and Stateof California, have invented certain new and useful Improvements inJewelers Tools; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertain's to make and use the same.

My invention relates broadly to improvements in tools, the subjectmatter of the present application being designed, however, for the useof jewelers and watchmakers. the device being so constructed as toprovide a number of so called bench keys of various sizes, confinednormally within a magazine, but capable of projection therefrom for thewinding of watch movements of various designs.

The object of the invention is to provide a tool which although beingextremely simple and therefore inexpensive, will be highly efficient anddurable and will possess a number of advantageous characteristics.

\Vith this general object in view, the invention resides in certainnovel features of construction and in unique combinations of parts to behereinafter fully described and claimed, the descriptive matter beingsupplemented by the accompanying drawings wherein like referencecharacters designate corresponding parts throughout the several viewsand wherein:

Figure l is a side elevation of a tool constructed in accordance with myinvention; Fig. 2 is an enlarged vertical longitudinal section thereofshowing one tool shank retracted and confined in the magazine; Fig. 3 isa similar view showing the same shank projected; Fig. 4 is a transversesection as seen along the plane indicated by the line 4-4 of Fig. 2;Fig. 5 is a similar view as seen along the plane indicated by the line55 of Fig. 3;I ig. 6 is a perspective view of one of the tool shanks andparts carried thereby.

In these drawings, the numeral 1 indicates a tubular magazine having atone end a chuck member 2 provided with a poly? sided central opening 3.The portion of the magazine 1 adjacent the chuck member 2, is providedwith a plurality of longitudiopenings o are formed through the magazine.The walls of the openings 5 constitute stop shoulders for engagement bystop members yet to be described.

Confined in the magazine 1 to be independently projected from onenendthereof, 1s a plurality of tool shanks 6 which are positionedeeeentrically and held in contact with the wall of said magazine, by thespring arms 7 which are integrally joined at their rear ends to the rearends of said shanks, the front ends of said arms being bent laterally asdisclosed at 8 to provide studs projecting through the several slots 1.The studs 8 pass through openings in leaf springs 9 and are either upsetor provided with suitable nuts, the latter being shown in the presentapplication. In the present embodiment of the invention, the springs 9are shown as formed by striking the intermediate portions of a pluralityof slide plates 10 outwardly, such plates being disposed over the slots4 in sliding contact with the magazine 1. I

It is the intention of the invention to project any one of theshanks 6through the poly-sided opening 3 in the chuck 2, and for so doing theinner end of said chuck is provided with a conical socket 11 into whichthe front ends of the several shanks project 1n spaced relation. It isfrom the apex of the socket 11, that the opening3 leads, it being thusevident that when one of the slides 10 is shifted in the properdirection, the shank 6 having connection with said slide Wlll beprojected forwardly, during which movement the front end of such shankcomes into contact with the inclined wall of the socket 11 and is thusgradually directed to the opening 3, the spring 7 allowing the shank 6to move in this manner as clearly disclosed in Fig. 3. L

For looking the shanks 6 in projected position, stops 12 are formed onchannelshaped members '13, the latter being dis posed astride on thefront ends of the spring arms 7 and having openings through which thestuds 8 project, the stops 12 being disposed for reception in theopenings 5 when the shanks are projected, whereby retraction of theshank in use is. prevented until the spring 9 having connection withsuch shank is forced inwardly by the thumb of the user. W ien this isdone, however, the spring arm 7 is forced inwardly, thus retr cting thestops 12 from the opening and allowing the shank to be again withdrawnby proper actuation of its slide.

The several shanks are of poly-sided formation conforming to the shapeof the opening 3, whereby when once projected, all strain for preventingrotation of the shanks independently of the magazine, will be exerted onthe chuck member rather than upon the spring arms 7. In the presentembodiment of the invention, the several shanks 8 are shown as providedwith rectan gular keys 1% which are used for the winding of watchmovements and are comn only termed bench keys. These keys are ofassorted sizes and in order that the proper key may be projected, theseveral slides 10 are inscribed with indicating characters as disclosedat 15, whereby he jeweler may ascertain at a glance which slide must beoperated to project the necessary tool.

The end of the magazine opposite that provi led with the chuck 2, isshown in the present embodiment of the invention as equipped with anadditional chuck 16 which preferably includes a pair of jaws I? forcedtogether by spring pressure and capable of being released by properactuation of a circular slide 18 which surrounds the magazine 1. t is tobe understood that the derice 16 is mounted upon the magazine only forthe sake of convenience and that the operation of the tool as previouslydescribed is affected in no manner by the presence of such device.

From th foregoing description, taken in connection with the accompanyingdrawit will be evident that although a very simple and inexpensiveconstruction has been. provided, the device will be highly ellicient anddurable and will possess a number of advantages.-

In the drawings, certain specific details of construction have beenshown for a complishing probably the best results and in the preceding,such details have been described, but it will be evident that I need notbe limited thereto otherwise than to that extent to which the appendedclaims restrict me. Furthermore, although the improved tool has beendefined as constructed for use of jewelers and watchmakers, it will beevident that numerous other devices could be well provided in place ofthe keys 1%, and that the entire tool could well be made in suchproportions as to accommodate such instruments as screw drivers, drills,etc.
